8GB DDR3 1333MHz CL7 kit for Alienware M15X

This 8GB kit contains two 4GB unbuffered SODIMM modules built for the Alienware M15X notebook. Each stick runs at DDR3 1333 (PC3 10600) with a CAS latency of CL7 and 1.5V voltage. The 204-pin form factor matches the system’s two memory sockets exactly.

Suitable for owners restoring an M15X to its 8GB

Buyers upgrading an Alienware M15X (DDR3 version) to the factory limit of 8GB will find this dual-channel kit a direct fit. A 64-bit operating system is required to address the full capacity. Systems needing ECC, registered modules, higher frequencies or larger capacities than 8GB cannot use this memory.

The 1333MHz CL7 DDR3 SODIMM specification decides

Only DDR3 1333MHz CL7 unbuffered 204-pin SODIMMs are compatible with the M15X DDR3 platform. Different speeds, latencies, voltages or pin counts will not work. Verify the notebook uses DDR3 before ordering.

Questions about this item

How much power does the 1.5V DDR3 kit draw when the Alienware M15X runs all day?

Each module operates at 1.5 volts, the standard DDR3 voltage, so total draw stays within the notebook's designed power envelope for 8 GB of memory.

What must the Alienware M15X already have for this 204-pin SODIMM pair to work?

The laptop needs two free 204-pin DDR3 SO-DIMM slots and a 64-bit operating system to address the full 8 GB capacity.

Will these CL7 sticks run stably beside the original 1333 MHz modules already in my M15X?

Yes, they match the 1333 MHz speed and CL7 timing of the factory memory, so the system will run all modules at the same frequency and latency.
